fuse alone, the latter ,only being used to explode the percussion-cap; nor can it be eX- ploded by lconcussionsuch `as blows against iron orstone. It will not freeze. It cannot vbe exploded by ralnming it in a bore-l10le,

nor by the application of flame; butjit may be ignited, yin which case it will burn Very slowly. It may be heated up to and above 100 centigrade without danger of,7 explosion.

If a fuse is applied to ignite it vvithout. the

use of percussion-cap, the fuse will burn out without igniting the powder. In order to cxplode, it must bc placed within a rigid inclus" pre, as before stated. lt will not explode when placed looselylupon a rock. For 'use I pnt'it-up in cartridges. It will not explode under any circumstances in the open air, Yeven -if a dynamite percussion-cap is uscd; nor will itexplode if strewn upon a red-hotiron plate, no1" in a cartridge, unless the latter be placed within rigid inclosure in the abs sence of air, as when used in bombs or other project-iles or in a rammed bore-hole, and

then only by percussion-cap ignited byfuse or electricity.
